this study was conducted to determine the effects of increasing lighting after peak production on eggs production and hatchable eggs in broiler breeder hubbard f15. in this research we used from 4 growing saloons, that in per saloons were 5250 hubbards broiler breeder hens. in this experiment we used by line design way of glm for analysed data, that we considered the effects of two parameters, ...

Background: Lighting is a basic need for human beings and affects their physical, physiological, and psychological behavior. The required level of lighting for visual performance must be provided in order to ensure health and wellbeing. Students spend much of their time studying in libraries, and thus, sufficient lighting is necessary in libraries. Therefore, the aim of the present study was to...

This paper analyses the office demand connected to the use of different dynamic window and lighting control systems with the aim to optimize their usage aspects and characteristics from both visual and energy efficiency viewpoints. The approach is based on an improvement of the non-commercial hourly simulation program IENUS. Results are referred to a typical office located in Mediterranean clim...

Due to the attenuation of light in water, deep-sea optical imaging system needs an active lighting provide source. However, because nonlinearity spatial dimension and spectral dimension, differs from terrestrial lighting. In order quantitatively analyze design system, we proposed a precise field simulation model method based on transfer function. Firstly, with analysis lighting-imaging process,...

lighting plays a key role in night escapes of urban spaces, in a way that it can be effective in giving identity to them. by considering this importance and inexistence of a process for composing urban lighting strategy made this study to be conducted by the objective of providing process for compilation of context-oriented lighting strategy in urban spaces. reaching a suitable solution for lig...

There is considerable well-intended, yet wishful anticipation about reducing greenhouse gas emissions by replacing fuel-based lighting in the developing world with grid-independent light-emitting diode (LED) lighting systems. Most estimates gloss over important practical realities that stand to erode a genuinely significant potential. The Clean Development Mechanism (CDM) is the leading system ...

The Energy Independence and Security Act of 2007 (EISA) and the increasing presence in the market of new lighting technologies like LEDs and EISA-compliant halogens are two factors that will likely lead to rapid change in the residential lighting market in the coming years—change that means hours-of-use (HOU) estimates based on specific lighting technologies are likely to become obsolete very q...
